10.5" x 13" - the right size for most small nearfield monitors.
"Your mixes are only as good as your monitors and mix environment. When I began using the Primacoustic Recoil Stabilizer I immediately noticed improvements in the low-end clarity of my near field monitors, to the point that I no longer needed to use a separate subwoofer. Incredibly, the detail of high frequencies and image localization were also improved."
